A soft-hand is an ace and any other card below the value of ten. This hand gets its name because the ace can be either one or eleven as necessary. The big advantage to a soft hand is that you can take hits with less risk of busing. But that doesn't mean you can be carefree about how you play your hand. Take a look at the dealers' showing card and play your cards as follows:
If you have an ace with an 8 or higher then hold your hand and don't take a hit. By playing the ace as 11 you have 19, which is a hand you should always stand on.
If you have an ace with 7 take a hit if the dealer's showing card is 9 or better.
If you have an ace with six or less then you should always take a bit. Even though this means you are taking a risky hit on 17 you can always bail yourself out if you bust by using the ace as a 1.
